Montano1993 [528]

Answer:

60%

Step-by-step explanation:

Given data

we are told that 24 canisters cost  $60

hence the cost per canister = 60/24= $2.5

The selling price per canister=  $4

%mark up = selling price-cost price/cost price *100

Substitute

%mark up = 4-2.5/2.5 *100

%mark up = 1.5 /2.5 *100

%mark up = 0.6 *100

%mark up = 60%

Hence the percent mark up is 60%

Please help is for now
telo118 [61]

Answer:

2

Step-by-step explanation:

Given:

-2(1-4x)=3x+8

Let's distribute the parenthesis

-2+8x=3x+8

Let's subtract -3x from both sides

-2+5x=8

Let's add 2 to both sides

5x=10

Now, let's divide both sides by 5 to get x alone

x=2

Hope this is helpful
